The Control implements a three-stage power algorithm during Box Temperature Control to 

minimize power consumption, improve temperature consistency, and minimize relay cycles. 
There are two Heaters available to heat the box: 900 W and 600 W. 
There are three stages of heat that can be used: 

Stage 1

 = 600 W

Stage 2

 = 900 W

Stage 3

 = 900 W + 600 W = 1500 W. 

When initially entering “HEAT” mode or if the user increases the “SETPOINT” while in 

“HEAT” mode, the Control uses Stage 3 to reach its setpoint as quickly as possible.
If, during any heating cycle, the setpoint is reached before 4 minutes elapse, the next 

heating cycle begins with the next lower stage. 
If, during any heating cycle, the setpoint is not reached before 8 minutes elapse, the 

control immediately uses the next higher stage and the next heating cycle will begin 

with that higher stage.

Humidity [Temperature]

Humidity [Temperature] is indicated on the right-hand 3-digit display, 

only

 in “PROOF” 

mode. 
Throughout this document, humidity refers to the Water Pan Temperature, since humidity is not 

directly sensed. 
In “HEAT” mode, “---“ is displayed. The Humidity Setpoint ranges from 1.0 through 9.0 with a 

resolution of 0.5. See Table 2.
